Embodiment Construction

[0019] Referring to the FIGURE, there is illustrated a simplified schematic process flow diagram for a process scheme, generally designated by the reference numeral 10, for the production of olefins, particularly light olefins, via oxygenate conversion processing. It is to be understood that no unnecessary limitation to the scope of the claims which follow is intended by the following description. Those skilled in the art and guided by the teachings herein provided will recognize and appreciate that the illustrated process flow diagram has been simplified by the elimination of various usual or customary pieces of process equipment including some heat exchangers, process control systems, pumps, fractionation systems, and the like. It may also be discerned that the process flow depicted in the FIGURE may be modified in many aspects without departing from the basic overall concept of the invention.

Abstract

Improved processing for the production of light olefins via oxygenate conversion processing is provided. Synthesis gas conversion such as to produce an effluent including at least methanol can be integrated with oxygenate conversion processing such as to produce an oxygenate conversion reactor effluent including at least light olefins and dimethyl ether. At least a portion of the oxygenate conversion reactor effluent can be contacted with such produced methanol to effect recovery of dimethyl ether from the oxygenate conversion reactor effluent.

Description

BACKGROUND OF THE INVENTION [0001] This invention relates generally to the production of olefins and, more specifically, to the production of olefins, particularly light olefins, via oxygenate conversion processing. [0002] A major portion of the worldwide petrochemical industry is involved with the production of light olefin materials and their subsequent use in the production of numerous important chemical products. Such production and use of light olefin materials may involve various well-known chemical reactions including, for example, polymerization, oligomerization, alkylation reactions. Light olefins generally include ethylene, propylene and mixtures thereof. These light olefins are essential building blocks used in the modem petrochemical and chemical industries. A major source for light olefins in present day refining is the steam cracking of petroleum feeds. For various reasons including geographical, economic, political and diminished supply considerations, the art has lon...
